微型水轮发电机内部流场模拟计算

Simulation of internal flow field of miniature hydro-generator

为了能够利用管道流体的动能,出现了一种适用于管道的微型水轮发电机,但是对于这种水轮发电机内部流场的研究却不充分,故针对这种管道微型水轮发电机进行几何建模,然后进行网格划分,对其内部流场进行模拟,得到压力云图、速度云图及速度矢量云图,研究其内部流体的运动状况及压力分布,并对其使用范围和方法提出建议。

In order to utilize the kinetic energy of the pipeline fluid,a micro hydroelectric generator suitable for pipelines has emerged,but the research on the internal flow field of this hydroelectric generator is not sufficient.In this paper,the geometric modeling of the pipeline micro-hydro-generator is carried out,and then the mesh is divided.Finally,the internal smoothness,and the pressure cloud,velocity cloud and velocity vector cloud map are obtained.Study the motion state and pressure distribution of the internal fluid,and make recommendations on its scope and method.
